Zion Williamson's knee injury 33 seconds into Wednesday's Duke-North Carolina game got Twitter humming among current and former NBA players. Many of them took direct aim at the NCAA system that makes hundreds of millions of dollars off athletes while paying them no salary.

Some current players recommended that Williamson shut his season down now in preparation for June's draft.

Let these kids go straight out of HS!!! Too much on the line to be messing with college if you got a legit chance to turn pro. One injury can change somebody career, Zion sit yo ass down lol and we will be ready for you in the big boy league #LookingOutForThePlayers
